Posted: Thursday 11th August 2011

Cheshire based Aquaflow a division of T-T Pumps are always prepared to leave their comfort-zone to deliver solutions that exceed expectations!

Belle Greve Pumping Station is undergoing an upgrade to prolong its lifespan, work started in 2008 and it is crucial to the islandís future sewage management programme. Aquaflow a division of T-T Pumps were approached by the principal contractor working on behalf of Guernsey Water because three DN600 wedge gate valves that had been supplied a few years ago by a framework manufacturer, had heavily corroded due to being in a saltwater environment.

These valves play a crucial role in controlling the flow and therefore it was very important they were put right as soon as possible. Following extensive discussions between Aquaflow and themselves, to ascertain hydraulic parameters and installation characteristics we proposed a solution endorsed with technical argument. T-T Pumps Aquaflow secured an order to supply three replacement DN600 gate valves that would with stand these arduous conditions. Aquaflow upgraded the seat and spindle nut material to aluminium bronze and spindle in super-duplex stainless steel. The ductile iron bodied valves were tripled coated in a marine grade two-pack resin to greater than 800 microns.
